The coral reefs of the Caribbean Dutch islands of St. Eustatius and Saba are of great ecological and economic importance. In the past decades the quality of these ecosystems, e.g. three-dimensional structure and the presence of key species herbivores, has severely declined due to anthropogenic impacts. To help restore the reef systems of the Dutch Caribbean windward islands, conservation organisations such as St. Eustatius National Park (STENAPA), Saba Conservation Foundation (SCF), Caribbean Netherlands Science Institute (CNSI) and many others started a new collaborative initiative for a new project together with Van Hall Larenstein, University of Applied Sciences. This project will deploy artificial reefs to study whether these reefs will support an increase of biomass and biodiversity on the existing natural reefs. AROSSTA brings low cost, non-invasive, and effective reef restoration, a significant step closer to reality.
